Is anyone familar with the wiring for the headunit on the supra?

[Stephen88]

I have an original supra head unit which I want to fit in , I was expecting it will plug straight into the car without any need of wiring looms. I have a wiring loom from the car to the after market pioneer radio which I have removed. But was suprised to see the plugs from the car (without the wiring loom) won't fit into the OE supra headunit.

 

Any ideas is there a harness from the car to the factory radio or has plugs been changed?

 

Thanks

Have the plugs to your aftermarket head unit been spliced into the head unit wiring? If so the plugs for the oem headunit have probably been cut off at the splice

Actually I think the 3 you are holding in your hand are for the amp. The should plug into a loom extender down by the bottom towards the footwell. Then a 4 plug/loom should come from this back to oem radio. I’m not sure there might be different radios that amps [emoji2369]

 

I hope the diagram makes sense
